A stunning example of a calcite ammonite fossil of the species Asteroceras obtusum from the world-famous Jurassic Coast beach of Lyme Regis, Dorset UK.
The piece of limestone matrix measures 90 mm (3.5 inches) across and the fossil ammonite measures 67mm (2.65 inches) across. The ammonite is well preserved and has been prepared out of the rock to reveal the whole shell. The ribs are very finely defined, and the colour is beautiful: light brown/orange in the gas chambers and a mix of mottled browns and greys in the body chamber. A crack in the shell has been stabilised. A great example of a popular species and impressive in the flesh. These ammonites are hard to get hold of in good condition these days. This is an iconic species from one of the most famous fossil locations on the planet.
Around 196 million years old (Sinemurian, Early Jurassic), this fossil would make a wonderful addition to any collection.
